pKa = -log Ka.
pKa = -log 1.8 x 10^-5
Take the log of 1.8 x 10^-5 by punching in 1.8 x 10^-5 and punching the log key.
pKa = -(-4.74473)
pKa = +4.74473
Then round to the correct number of figures. I typed all the numbers that showed on my screen so you could see if you were punching in the right keys.
